Kev Taw Qhia
Cov hlau tsis xeb yog cov hlau uas muaj cov hlau sib xyaw ua ke ntau. Cov hlau no muaj plaub pawg xws li cov hlau martensitic, austenitic, ferritic thiab cov hlau uas tau kho kom ruaj khov. Cov pawg no yog tsim los ntawm cov qauv crystalline ntawm cov hlau tsis xeb.
Cov hlau tsis xeb muaj cov chromium ntau dua piv rau lwm cov hlau thiab yog li ntawd muaj kev tiv thaiv xeb zoo. Feem ntau ntawm cov hlau tsis xeb muaj li ntawm 10% ntawm chromium.
Qib 2205 stainless hlau yog ib hom hlau stainless duplex uas nws tsim ua rau muaj kev sib xyaw ua ke zoo dua tiv taus pitting, lub zog siab, kev ntxhov siab corrosion, crevice corrosion thiab tawg. Qib 2205 stainless hlau tiv taus sulfide kev ntxhov siab corrosion thiab chloride ib puag ncig.
